After 4 hard track days and plenty of hard street use, these coil overs really proved to have top quality reliability and amazing performance. Having a car that sits higher up than most track cars, these coil overs make the car feel planted in every corner and give great feedback at each wheel. Any questions or concerns I have had, Jerrick was able to help me sort things out super quickly. Best suspension set up I have ever ran, worth every penny. Bang for your buck.
